Chem and Physics labs
Re: Chem and Physics labs
I think the titration race makes it sound like fun. in class whenever we have to do a titration my friends and i always race. it's not super accurate, but its fun!

Re: Chem and Physics labs
Yeah, it's not that difficult...and is probably way overcurved. Hopefully, the judges will find a way to score it fairly. To practice, just make someone on your team make an acid/base of some given molality and then do the titrations. Try to do it at least once with each of: a pH probe, phenolphthalein, burettes, and pipettes. Just get a good method with your partner that won't leave one of you doing nothing while the other does the whole titration.
I wouldn't expect diprotic acids for the titration race, but I'd prepare for them for the rest of the labs/questions. They could do more than one titration the way the rules are written.

Re: Chem and Physics labs
It means that you have to do the titration more than once (probably, three times would be a good number).
Standard deviation is the square root of the sum of the deviations of each trial the mean of all trials divided by one minus the number of trials....yeah...look here

Re: Chem and Physics labs
This is my first year doing the Chem. Lab and I am really excited. I am a sophomore this year but last year a senior competed for us so I am a tad worried but titration is always fun. We completed a long titration lab in November in my Organic class and I thought it was really neat. Hopefully, my skills are too poor for a race! Any suggestions?

Re: Chem and Physics labs
You dont need to study much for physics lab. The test is a joke. The main thing you need to have is a fan that can generate a heck of a lot of voltage

Re: Chem and Physics labs
It isn't really a race per say, I do believe that the time is a tie breaker.
